STREET-SWEEPER.

Specification of Letters Patent.

Patented June 24:, 1919.

Application filed September 11, 1916, Serial No. 119,356. Renewed October 15, 1918. Serial No. 258,289.

To all whom it may concern:

Be it known that we, CHARLES FINKEL and IRA COHEN, citizens of the United States,

and residents of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Street-Sweepers, of which the following is a full, true, and exact specification.

Our invention relates to improvements in street sweepers and has for its principal obj ect to provide an improved and novel form of street sweeping device which embodies means for conveying and elevating the sweepings into a cart or Wagon. Another object of our device is to provide swee ing means and elevating means both of w ich are operated from the traction wheels of the device. It is usual in rotary brush sweepers to brush the dirt into piles or windrows after which it is shoveled into the cart or wagon. Our device is designed to load the dirt directly into the wagon as it leaves the brush, thereby obviating the necessity of shoveling the dirt into the wagon.

In the drawings Figure 1 is a plan View of our device with parts broken away and others omitted. Fig. 2 is a sectional side elevation of same.

Referring more particularly to the draw ings, numeral 1 indicates a wagon bed or box which is mounted upon a front truck having wheels 2 and upon a rear axle 3 to which is secured traction wheels 4:, drive gears 5 and secured to the inner side of wheels 4 and revolved therewith. Brush hangers 6 are revolubly mounted upon shafts 3 adjacent the gears 5 and supporting a brush shaft 7 at the outer ends. A rotary sweeping brush 8 is secured to shaft 7 which is caused to revolve by means of pinions 9 which mesh with gears 5. Brush raising and lowering mechanism may be provided in a form of rod 10, bell crank 11 and hand rod 12. Conveyer hangers 13 are revolubly mounted upon shaft 3 and support a conveyer shaft 141 and stub shaft 15. Pinions 16 and 17 are mounted upon stub shafts 15, the former engaging the gears 5 and the latter engaging conveyer pinion 18, which are secured to the conveyer shafts 14'. An endless conveyer 19 passes around a roller 20 which is secured to the conveyer shaft 14. The conveyer also passes around a head roller 21 which is mounted upon the body 1. A brush apron 22 is pivotally secured to hangers 13 and normally Copies of this patent may be obtained for bridges the space between the brush 8 and the conveyer 19. Conveyor raising means in the form of a rod 23, bell crank 2 1 and hand rod 25 may be used to raise the hangers 13 and thereby release the tension on the endless conveyer. It will be apparent from the description that our device is operated entirely from the traction wheels 4 and that the brush may be raised and lowered into contact with the surface of the road at the will of the operator. Also the conveyer hangers may be raised and lowered to suit the tension of the conveyer belt. In operation the brush 8 sweeps the dirt rapidly up and over the apron 22 and on to the endless conveyer belt 19, which in turn carries the dirt up and over the head roller 21 and deposits it in the box 1. There is some available space in the box 1 behind the conveyer which may be utilized for carrying rubbish, etc,

While we have shown a particular form of embodiment of our invention, we are aware that many minor changes therein will readily suggest themselves to others skilled in the art without departing from the spirit and scope of the invention, and we therefore desire to avoid being limited to the exact form shown and described.

Having described our invention, what We claim as new and desire to protect by Letters Patent, is

In a rotary street sweeper having a wagon body mounted upon front and rear axles, the combination of hangers mounted on the rear axle and extending rearwardly and downwardly therefrom, a rotary sweeper supported in the hangers, meansfor raising and lowering the sweeper, conveyer supporting hangers mounted on the rear axle and extending forwardly and downwardly therefrom in front of the sweeper, a roller mounted between the conveyer supporting hangers, a roller mounted in the wagon body, a continuous conveyer passing around the two rollers and extending through the wagon body, a gear Wheel on the rear axle,

gearing on the conveyer hangers meshing with the gear on the rear axle, and means connected to the conveyer supporting hangers 'to raise and lower the lower end of the conveyer.
